Supported options: .Bl -tag -width Ds .It Xo .Fl v , .Fl -verbose .Xc Verbose output. .El .Pp .Ar command can be one of the following: .Bl -tag -width srvconvert .It add Xo .Op Fl p Ar principal .Op Fl -principal= Ns Ar principal .Op Fl V Ar kvno .Op Fl -kvno= Ns Ar kvno .Op Fl e Ar enctype .Op Fl -enctype= Ns Ar enctype .Op Fl w Ar password .Op Fl -password= Ns Ar password .Op Fl r .Op Fl -random .Op Fl s .Op Fl -no-salt .Op Fl H .Op Fl -hex .Xc Adds a key to the keytab. Options that are not specified will be prompted for. This requires that you know the password or the hex key of the principal to add; if what you really want is to add a new principal to the keytab, you should consider the .Ar get command, which talks to the kadmin server. .It change Xo .Op Fl r Ar realm .Op Fl -realm= Ns Ar realm .Op Fl -a Ar host .Op Fl -admin-server= Ns Ar host .Op Fl -s Ar port .Op Fl -server-port= Ns Ar port .Xc Update one or several keys to new versions. By default, use the admin server for the realm of a keytab entry. Otherwise it will use the values specified by the options. .Pp If no principals are given, all the ones in the keytab are updated. .It copy Xo .Ar keytab-src .Ar keytab-dest .Xc Copies all the entries from .Ar keytab-src to .Ar keytab-dest . .It get Xo .Op Fl p Ar admin principal .Op Fl -principal= Ns Ar admin principal .Op Fl e Ar enctype .Op Fl -enctypes= Ns Ar enctype .Op Fl r Ar realm .Op Fl -realm= Ns Ar realm .Op Fl a Ar admin server .Op Fl -admin-server= Ns Ar admin server .Op Fl s Ar server port .Op Fl -server-port= Ns Ar server port .Ar principal ... .Xc For each .Ar principal , generate a new key for it (creating it if it doesn't already exist), and put that key in the keytab. .Pp If no .Ar realm is specified, the realm to operate on is taken from the first principal. .It list Xo .Op Fl -keys .Op Fl -timestamp .Xc List the keys stored in the keytab. .It remove Xo .Op Fl p Ar principal .Op Fl -principal= Ns Ar principal .Op Fl V kvno .Op Fl -kvno= Ns Ar kvno .Op Fl e enctype .Op Fl -enctype= Ns Ar enctype .Xc Removes the specified key or keys. Not specifying a .Ar kvno removes keys with any version number. Not specifying an .Ar enctype removes keys of any type. .It rename Xo .Ar from-principal .Ar to-principal .Xc Renames all entries in the keytab that match the .Ar from-principal to .Ar to-principal . .It purge Xo .Op Fl -age= Ns Ar age .Xc Removes all old versions of a key for which there is a newer version that is at least .Ar age (default one week) old. .It srvconvert .It srv2keytab Xo .Op Fl s Ar srvtab .Op Fl -srvtab= Ns Ar srvtab .Xc Converts the version 4 srvtab in .Ar srvtab to a version 5 keytab and stores it in .Ar keytab .
